y, My presentiiiventioii` relates toa joint for metallic members which is particularly adapted for locking together metalsheets in theV formation of a tin or nietal roof.

Theprineipal obj eetl of the invention is the provisionofa ljoint `of the typeHdescribed whichv willbe ,watentightiwhich will permit of the sheetsbeing seouredto the wooden roof sheathing without ythe'fsecuring means passing through the sheets themselves, and which provides a lock for ,the abutting' parts.

Anotherimportant object of the invention is the provision' ofaoonstruetion which will permit ready separation of the parts should the same `be necessary' without mutilation of the metal strips so that they may beragain used. l

To this end the invention contemplates a metal roof comprising elongated sheet elements having their eXtremeA longitudinal edges formed into an upstanding wall having l a returnlbent portion turned back towards the niain body or sheet. `This bend may be either sharp or arcuate. In use tivo of these longitudinally extending sheets will be placed adjacent to each other so that the upstandiiig wall along one longitudinal edge oi. each of two sheets will substantially -abut each otlier, the return or bent portion of each wall extending in thev opposite direction. I have found it desirable tolprovide' a cleat or fastening element having an upstanding wall and a return bent portion adapted to partially overlie the bend in one of the longitudinal edge portions of the main rooiig element, the remainder of the cleat adapted to lie flat upon the roof sheathing and to be nailed thereto. Tith such a construction, a second elongated sheet member may thon be placed in position with the main body of the cleat underlying the saine, the relation of the upstanding Wall on the two adjacent sheet members existing as before.

A cap having offsetlocks therein may now be snapped over the two return bent portions of the sheet members, the oifset looks engaging and opposing the raw edge the return beni persons: v Thispcap erect-italy locks the two sheet elementstogeth'er, ,and makes fthe ]oint between the two upstanding walls, of

waterproofnature. V

The invention further consists in the novel arrangement, construction, and Combination of parts hereinafter described.. and shownin the accompanying drawings;l irifwhich` Y y Fig. 1 is a sectionalvie'w'oflfa device embodying the invention. 4

The opposite longitudinal edge of the sheet A is likewise provided with the same upstanding wallv and return bent portion.y The body 1 is adapted to lie upon the ordinary roof sheathing.
